Falls out and you would take it with your hands and that doesn't make it good in the corona times
Not sure if this works, people unfortunately see it and ask about it and it doesnt stay all day so you would touch it with your hand and that is not good

I am now happy with them... but..
I am now satisfied with these but you should basically ignore the fitting guide. These are meant (apparently) to be fully inserted in the nostrils with the plastic half-ring tight against your septum. For me - as soon as i tried fitting them this way it wasn't long before at least one of the filters would turn side-ways in one of my nostrils resulting in ineffective filtration. There doesn't seem to be anything to grip them and keep them in place when fully inserted. However - what i noticed was is that there is a groove in the design of the filters. I found that by inserting them at the very edge of my nostrils i could get this groove to slot in-between and grip the cartilage at the entrance of the nostrils. I have demonstrated this with some pictures that i have added. Once slotted in place at the entrance of the nostrils they stay put (at least for me) but ONLY if you purchase a size one size larger than actually fits you. I initally bought the medium size - which was about the right size for me and although these slotted in ok and were comfortable there was still enough 'play' in them to eventually work themselves loose, (but not always). I then bought the large size - at first i found them uncomfortable as they really did stretch my nostrils but i soon got used to this. I also found them MUCH easier to breath through than the medium set as my nostrils were being forced wider. The extra size kept them firmly in place and they have not come loose since. The only difficulty is in the initial fitting as the larger size takes some practice to slot into place. Although they are more noticeable when inserted at the entrance of the nostrils they are still far less noticeable than walking around with a face mask on all the time. Once used i then remove them and clean them with an alcohol wipe and store them in the provided carrying case. I keep using the same set until they begin to darken and then i switch to a new set. I have also noticed that if i breath in through my nose and out through my mouth i get less 'runniness' in my nose. It is a real pain having to remove them to blow your nose. All in all i am now happy with them and i will continue to use them - i hope this review has been helpful.

They fall out & design makes unwearable
I was to get these nasal filters because I thought I had found a product that would actually work. However I was really disappointed with this. First of all the design is incredibly uncomfortable they do not stay in your nostril. You have to have a really wide nostril for the filters to fit. Even when I shoved them in halfway up my nose they still would not fit so they were basically a complete waste of money because you cannot wear them I am shocked that they had good reviews and I would recommend something different. Either invest in a mask to wear over your face or invest in some sort of allergen blocking nasal gel I have bought a great allergen blocking nasal gel from Amazon they have many different types but for me it’s a great product because it does seem to cut down on the allergens entering my body and I noticed that when I wear it I do not get the symptoms that I normally would if I wouldn’t wear it for example when I don’t wear it my nose will run I will get a headache I will get congested and I’ll feel tired when I put it on in the morning. After bathing and having my nose Celine rinsed it is really really effective for me especially with my problems and sensitivities to mold

uncomfortable
Really difficult to fit in the nostrils in the way that prevents it from falling off.
